项目摘要
Australian coastal soils often pose significant challenges in the design and construction of railways. The project aims to develop a novel hybrid system of pipe piles & prefabricated vertical drains installed to prevent soft foundation soil (subgrade) from excessive yielding under prolonged cyclic loading by heavy-haul trains. Using large-scale physical model simulations and field trials supported by numerical analysis of soil-pile-drain interaction mechanisms, this innovative concept will be examined to establish a user-friendly design methodology. For rail operators, the outcomes will generate substantially reduced maintenance costs, while extending the longevity of track infrastructure to ensure faster and heavier trains of the future.
澳大利亚沿海土壤经常对铁路的设计和建设构成重大挑战。该项目旨在开发一种新型的管桩-预制垂直排水沟混合系统,以防止软土地基(路基)在重载列车长时间循环荷载下过度屈服。利用大规模物理模型模拟和现场试验,并辅以土-桩-排水相互作用机理的数值分析,将检验这一创新概念,以建立一种用户友好的设计方法。对于铁路运营商来说,这一结果将大幅降低维护成本,同时延长轨道基础设施的寿命,以确保未来更快、更重的列车。
